receiving user login information, wherein the user login information comprises a user job number and a name;
popping up a password box according to the user login information;
receiving a user input character;
calling a preset password character;
judging whether the characters input by the user are consistent with preset password characters or not;
if the judgment is consistent, jumping to an examination interface;
and if the judgment result is inconsistent, maintaining the current interface.
6. The signature authentication method for construction drawing inspection according to claim 1, further comprising receiving user login information, and thereafter:
shooting a user face image, wherein the user face image is shot by a camera loaded on a server;
calling a preset face image in a database;
judging whether the face image of the user is consistent with a preset face image or not;
if so, jumping to an examination interface;
if not, the current interface is maintained.
7. A signature authentication system for construction drawing examination is characterized by comprising:

the to-be-examined information identification module (400) is used for identifying the to-be-examined information;
the preset information calling module (500) is used for calling the preset information from the database;
the judging module (600) is used for judging whether the information to be checked is consistent with the preset information or not;
the signature authentication success information module (700) is used for generating after judging that the signature authentication success information module is yes according to the judging module;
and the signature authentication failure information module (800) is used for generating the signature authentication failure information according to the judgment of the judging module.
8. A computer device, characterized by: comprising a memory and a processor, said memory having stored thereon a computer program which can be loaded by the processor and which performs the method of any of claims 1 to 6.
9. A computer-readable storage medium characterized by: a computer program which can be loaded by a processor and which executes the method according to any of claims 1 to 6.
